摘　　要：冠状动脉CT血管造影(CCTA)是目前常用的冠心病无创诊断方法,但有一定的假阳性率,导致不必要的有创冠状动脉造影。CT血流储备分数(CT-FFR)是通过对CCTA图像的进一步处理和计算对缺血做出功能性诊断,多项研究已证实了其诊断稳定型冠心病的准确性及临床可行性和安全性,但也有一些不足和限制。Coronary CT angiography(CCTA)is a commonly used non-invasive diagnostic method for coronary atherosclerotic heart disease,but it has a certain rate of false positive,resulting in unnecessary invasive coronary angiography.CT-derived fractional flow reserve(CT-FFR)is a functional diagnosis of ischemia by further processing and calculating CCTA images.Many studies have confirmed the accuracy,feasibility and safety of CT-FFR in the diagnosis of stable coronary heart disease,however,there are still some shortcomings and limitations.
